A bitter Twitter spat ensued, culminating most recently with Rowling sharing a screen grab of an article singing her praises and achievements, writing yesterday “Just been sent this! Could the writer let me know who he is? I’d love to thank him! #Valentines.”

Meanwhile, Morgan’s son and Daily Mail football commentator Spencer has joined the row – seemingly taking Rowling’s side by sharing a photo of his Harry Potter tattoo of the ‘Deathly Hallows’ symbol with the caption “well this is awkward”.
